Morphlogy of melt-kneaded blends of amorphous nylon (AmPA) and poly(styrene-co-acrylonitrile) (SAN) was investigated by scanning electron microscopy. Co-continuous morphology was observed for the SAN/AmPA blends in which volume fraction of SAN was nearly equal to that of AmPA. It was found that the continuous structures tend to be enlarged or changed to matrix-droplet morphology with increasing shear rate. In addition, sizes of droplets in SAN/AmPA blends taking matrix-droplet morphology were independent of shear rate and strongly depend on blend composition.
